I'm lacking energy to follow my study schedules
Basically, ever since school has reopened, they've been conducting tests non-stop. Now, my concern is, I don't feel pressurized to study but I feel like I have no energy at all to have a presence of mind and put my focus on my studies. Sometimes, I'm motivated and complete my tasks asap. And the other times, well, like now, I'm lacking focus so bad. My mind feels so occupied but when I ask myself what is actually occupying the space, I genuinely get no idea. There's literally nothing that's stressing me out rn. But I know that I don't have the energy to be productive. It's even reacting on my body. It's like I have to drag myself to even get basic actions done. I feel super demotivated. I do sleep averagely okay like 6+ hrs mandatory. I do take good amount of water everyday. I meditate for sometime. I move quite a lot as well. But after school, when I reach home, I feel completely drained. My mind feels like it won't work until it gets energy to stay productive. I don't even feel the feeling of existing. It's like I had alcohol or smth. It legit feels that way.
Now, what do I do to get myself on track?
